Evaluation of Centering Ability in Artificially Curved Canals with Three Thermomechanically Treated NiTi Instruments: Blue, Pink and Gold.
Article in Iranian endodontic journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The present study aimed to evaluate the instrumentation time and transportation ability of three file sequences sharing the same physical properties (diameter, tip design, cross-sectional shape, and taper), each manufactured entirely of one single alloy type (Pink, Blue, or Gold). Materials and Methods: One hundred and eighty simulated curved resin canals were instrumented using the BlueShaper system, with full Z1-Z4 sequences, each made entirely of a single alloy type (Pink, Blue, or Gold). Images before and after instrumentation of each specimen were overlaid with Photoshop software to evaluate centering ability in the coronal, middle, and apical thirds. Data were analyzed using one-way analysis of variance (ANOVA) with post hoc multiple comparisons or the non-parametric Kruskal-Wallis test for intergroup analysis. Results: No significant differences were found between the different alloys in the centering ability of the simulated canals in the coronal third ( Conclusions: It was concluded that the Blue alloy performed better than the Pink and Gold alloys in the middle and apical thirds. The pink alloy performed better than the Gold alloy in the apical third.
